Pillow

ABSTRACT

The invention relates to a pillow, which comprises a pillowcase; wherein the pillowcase is internally provided with a pillow inner, a transverse opening is formed at the middle position of the surface of the pillowcase, surplus pillowcase materials are reserved at the opening, and the opening is connected via reserved surplus materials; a groove is formed at the front position of the bottom of the pillow inner, and inserts stiffer than the pillow inner are embedded at the groove position. The pillow provided in the invention is provided with an opening at the position of the back of the head on the pillowcase, so that the pillow inner is better concaved, and the comfort of the back of the head can be increased. Moreover, rigid inserts are arranged at the front position of the bottom of the pillow inner to support the cervical vertebra.

BACKGROUND OF THE INVENTION

The invention relates to a pillow, which belongs to the technical field of bedding.

Being a life necessity, the comfort of a pillow leaves great influence on the sleeping quality and the cervical vertebra of people. At present, some products are made to be the same as or similar to the shapes of the neck and the back of the head in the market, which gives a feeling that they fit for the shapes of the cervical vertebra and the back of the head; while in the actual application, due to the stress by human weight, the shape of the pillow deforms completely, thereby not achieving the effect of fitting for the shapes of the neck and the back of the head. The most important reason for it lies in the hardness of the material, because the materials for the pillows are the same. If the material of the pillow is made into the best hardness to support the back of the head, the back of the head will be more comfortable owing to the softness of the pillow, but the neck can still not be effectively supported also due to the softness of the pillow, which will bring muscular tension and aching pain at the neck. If the material of the pillow is made into the best hardness to support the neck, although the neck is effectively supported, the back of the head will not be comfortable because the pillow is too hard, which will lead to head tumefaction or anaesthesia.

BRIEF SUMMARY OF THE INVENTION

The invention provides a pillow which can increase the comfort of the back of the head and support the cervical vertebra.

In order to realize the above purposes, the invention provides the following technical scheme:

A pillow comprises a pillowcase, wherein the pillowcase is internally provided with a pillow inner, a transverse opening is formed at the middle position of the surface of the pillowcase, surplus pillowcase materials are reserved at the opening, and the opening is connected via reserved surplus materials;

A groove is formed at the front position of the bottom of the pillow inner, and inserts stiffer than the pillow inner are embedded at the groove position.

Wherein, preferably, a plurality of small round holes are formed on the pillow inner.

Wherein, preferably, the front part of the pillow is a downward and outward bevel surface.

Wherein, preferably, inward concave arc shapes are arranged on the left side and the right side at the front position of the pillow.

According to the above technical scheme, the pillow provided in the invention is provided with an opening at the back of the head position on the pillowcase, so that the pillow inner is better concaved, and the comfort of the back of the head can be increased. Moreover, rigid inserts are arranged at the front position of the bottom of the pillow inner to support the cervical vertebra.

DETAILED DESCRIPTION OF THE INVENTION

To better understand the technical scheme of the invention, the detailed description of the invention will be given hereinafter with reference to the attached figures.

The invention provides a pillow. As shown in FIG. 1 and FIG. 2, the pillow comprises a pillowcase 101, the pillowcase 101 is internally provided with a pillow inner 107, a transverse opening 102 is formed at the middle position of the surface of the pillowcase, surplus pillowcase materials are reserved at the opening 102, and the opening 102 is connected via reserved surplus materials, namely, the pillowcase 101 is connected via materials the same as the pillowcase 101 at the opening 102; a groove is formed at the front position of the bottom of the pillow inner 107, and inserts 105 stiffer than the pillow inner are embedded at the groove position. The pillow inner 107 is made of low resilience recovery material, and the inserts 105 are made of high resilience recovery material.

When the pillow is under the stress from the human body, and the pillowcase 101 is depressed together with the pillow inner 107; at this time, the pillowcase 101 will be tightened at the front side and the rear side; because the pillowcase 101 itself can not be depressed, it can only be tightened at the front side and the rear side or at the four sides when being under a stress from an external force, therefore, surplus pillowcase materials are reserved at the opening 102 to provide a space for the pillowcase 101 to be depressed, so that the pillow inner 107 can not deform and the comfort of the back of the head can be improved; because of certain hardness, the inserts 105 can support the position of the cervical vertebra. Therefore, the pillow is more comfortable when in use. Therefore, the best hardness of the pillow inner can be achieved, the curve and the contour of the neck can be completely adapted, the muscle, the blood and the nerve can be relaxed, the cervical vertebra can be well protected, the sleeping can be promoted, the sleeping comfort can be improved, and the sleeping environment can be improved.

In a further embodiment, in order to enhance the softness of the pillow and make the back of the head more comfortable, a certain number of small round holes 106 are formed in the middle of the pillow inner, so as to reduce the resistance, increase the softness of the pillow and make the back of the head more comfortable owing to the softness of the pillow.

In the further embodiment, as shown in FIG. 3 and FIG. 4, the front part of the pillow is a downward and outward bevel surface 104, so that a certain transitional slope is formed between the cervical vertebra and the body to increase the comfort of the cervical vertebra.

Besides, in another embodiment, inward concave arc shapes 103 are arranged on the left side and the right side at the front position of the pillow. When the user sleeps on the side, the shoulder can be effectively avoided from pressing the pillow, and simultaneously, the gap at the shoulder can be filled appropriately to avoid the common problem of air infiltration of the quilt at the shoulder, thereby effectively preventing cervical spondylopathy.

For the ordinary technical personnel in the technical field, the above description to the pillow provided by the embodiment of the invention can be changed in the specific implementation and application range according to the concept of the embodiment of the invention. In sum, the content of the description shall not be considered as limiting the invention.
